I've been having trouble getting the following C++ program to work
using the current 3.0 CVS. I've installed with --prefix=/usr, after
purging all of the existing /usr/include/g++* directories. I'm on an
i686-linux(2.4.3)-gnu(2.2.2) box.
Here's the program:
#include <iostream>
int main() {
cout << "hello, world!";
; return 0; }
Here's what I get.

Ok it seems that the g++ include files are no longer part of the default include
search path, so I tried:

Sure enough, there is no bits/c++config.h file in
/usr/include/g++-v3/bits, but there is one in
/usr/include/g++-v3/i686-pc-linux-gnu/bits/ and if I link the file(s)
there to the g++-v3/bits directory, most of the errors go, with the
exception:
/usr/bin/g++ -v -Wall -save-temps -I /usr/include/g++-v3/ test.C
test.C: In function `int main()':
test.C:3: `cout' undeclared (first use this function)
test.C:3: (Each undeclared identifier is reported only once for each function
it appears in.)
